The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympathetic innervation from celiac ganglion. http://en.wikipedia.org/wiki/Pylorus
The valve preventing the movement of chyme from the duodenum into the stomach is called the pyloric valve. The pyloric valve consists of a ring of smooth muscle and is connected to the duodenum.

The Pylorus (the valve between the stomach and duodenum is the pyloric valve)
It serves to regulate the movement of food out of the stomach and prevents bile in the small intestine from moving back into the stomach.
The duodenum is the valve between the stomach and the small intestine.
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
The pyloric valve, or pyloric sphincter, is a muscular valve located at the junction between the stomach and the small intestine. Its primary function is to regulate the passage of partially digested food (chyme) from the stomach into the duodenum, the first part of the small intestine. By opening and closing, the pyloric valve ensures that the chyme is released in a controlled manner, allowing for proper digestion and absorption of nutrients while preventing backflow into the stomach.
The stomach and first part of the small intestine (duodenum) is connected by pylorus which has 2 parts. The on the stomach opening is called pyloric antrum and the opening in the duodenum is the pyloric canal type.
The pyloric valve is located between the stomach and the small intestine. It regulates the flow of partially digested food (chyme) from the stomach into the small intestine for further digestion and absorption.
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
